Craving more sunny, spring-like weather?

Don’t get your hopes up.

Cold weather rules again this week in New Jersey, and there’s a chance of light snow on Wednesday, according to the National Weather Service.

Arctic air is spawning temperatures 10 to 30 degrees below normal across the northern third of the nation today, with the coldest air west of New Jersey, according to the weather service[2]. The cold air will slowly move eastward by midweek.

Low pressure is forecast to develop off the Carolina coast Tuesday night before moving out to sea, according to a Mount Holly Office forecast discussion[3]. Forecast model trends keep pushing the fast-moving storm toward the east-northeast, with little impact on our region.

In general, 1 to 3 inches of snow is expected in our region on Wednesday morning, but some spots could get closer to 4 inches, according to the discussion.

The weather service forecast for Neptune [5]says there’s a 40 percent chance of snow after 1 a.m. Wednesday, with less than a half-inch possible. Then there’s a 50 percent chance of snow on Wednesday, with 1 to 2 inches of snow possible.
